Definitions

  • the present invention relates to an elastic hinge for spectacles connecting a branch to a glass frame facade.
  • Such hinges elastic give a snap effect when passing the branches of their so-called “open” position for wearing glasses in their "closed” storage position, and allow the branches to be elastically spread outwards beyond their "open” position.
  • These hinges are very popular with the public, especially because that they maintain good geometry of the frame even if it is frequently used, and the fact that the branches press against the temples with reasonable pressure.
  • an elastic hinge is composed on the one hand a front knuckle fixed securely in the lateral tenon of the facade, and other part of a branch knuckle connected by or with an elastic return mechanism to the end of the branch, an axis ensuring the connection between the knuckles.
  • a first type of known return mechanism comprises a slide movable in translation inside a housing provided or reported at the end of the branch, the emerging end of the slide bearing a male or female knuckle.
  • the other cam-shaped front knuckle is in support against the mouth of the housing. Behind the scenes a space is created longitudinal so as to accommodate a spring with its rear end supported against the rear wall of the slide, and whose front end comes to rest against a stop made integral with the housing, such as an axis, a pin or a screw crossing.
  • a stop made integral with the housing such as an axis, a pin or a screw crossing.
  • This type of hinge elastic is, for example, described in the documents EP 0 091 573, FR 2 258 642, FR 1 511 263, EP 0 426 947 and FR 2 702 573.
  • the branch knuckle is formed at the emerging end of a central rod movable in translation inside a housing provided or attached to the end of the branch.
  • the cam-shaped female front knuckle is in support against the mouth of the housing.
  • a spring threaded around this rod central is supported on one side against an extra thickness made at the end of the rod, and on the other side against a pin passing through the housing or against a stop snapping into the inside of the housing to act as a restriction.
  • the front knuckle pushes the housing, which causes an elastic release of the rod.
  • This type of elastic hinge is, for example, described in documents EP 0 340 161, FR 2 609 816 or FR 2 664 990.
  • the end of the branch in which is formed, or against which is attached, the housing of the mechanism therefore necessarily has a cross-section consequent minimum transverse, both in width as seen in the direction perpendicular to the wearer's temple and in the height as seen in the direction parallel to the wearer's temple and perpendicular to the longitudinal direction of the branch, since this section is the sum of those of the spring, the slide and peripheral housing walls in the first case, or the sum of the rod, of the spring and of the peripheral housing walls in the second case.
  • Such hinged frames and ends of bulky branches are then frequently considered too unsightly by many buyers potentials however eager to benefit from the elastic effect.
  • a third type of elastic hinge described in document FR 2 517 080, includes a male knuckle formed directly at the end of a branch in the form of a cylindrical metal rod, and connected by a screw to a female knuckle secured to the facade. Sliding mounted scabbard on the cylindrical rod close to the male knuckle is normally pushed in the direction female knuckle by a spring also concentric with the cylindrical rod and bearing at the rear against a stop integral with this branch, such as a crimped ring or glued branch envelope.
  • the sheath has an external extension coming to bear against a stop also outside the front tenon to achieve an effect elastic beyond the open position.
  • a flat front face of this sheath is pushed against a front knuckle cam-shaped female which therefore pushes back the sheath by compressing elastically the spring during a rotation of the branch between the open position and closed.
  • the cross section of the corresponding end of the branch is therefore reduced to that of the rod and the coaxial sheath.
  • this mechanism is relatively long as seen in the longitudinal direction of the branch in the measurement where the sleeve, the spring and the stop ring are one behind the other. Above all, this mechanism is only applicable for branches whose end is reduced to a simple cylindrical metal rod.
  • the object of the present invention is a spectacle hinge, the elastic mechanism fits particularly well into a branch end flat, especially horizontal. This mechanism must be able to ensure effective elasticity beyond the open position and / or a second elasticity between the open and closed branch positions, and this while respecting the appearance "flat fluid" to appear as discreet as possible, becoming, the if necessary a decorative element.
  • such a hinge must be achievable in small dimensions, especially of metal, and should include as much as possible a reduced number of simple, solid and inexpensive parts.
  • this hinge must be arranged in such a way that they are reasonably easy to assemble or even disassemble in the event of repair.
  • an elastic hinge of glasses comprising on the first side, for example at the end of the branch, a male knuckle and on the second side, for example on the front tenon, a female knuckle connected to the male knuckle by a connecting axis, characterized in that, when the periphery of the male knuckle on the first side is cam-shaped, the orifice for passage of the axis of connection of the male knuckle is in the form of a longitudinal lumen oriented towards the periphery in the form of a cam, and in that a spring housed in the lumen acts between the bottom of this light and connecting pin to push the cam-shaped periphery of the male knuckle against the bottom of the female knuckle or in that, when the periphery of the eyelets of the female knuckle on the second side is in the form of a cam, the flat end of the first side has, near the male knuckle, a
  • this mechanism can be remarkably short. It only takes one hand to bring the front end of the light closer to the front faces of the part external sliding very close to the female knuckle, and secondly to choose a effective spring but also short.
  • we remove the ring rear spring stop and the spring and the external sliding part are superimposed equivalent to the scabbard.
  • the sliding external part is present in the form of two plates on either side of the flat end and joined by an internal male jump crossing the light in front of the spring, plates of which at least one of the two front edges bears against the female knuckle.
  • the two symmetrical plates each have a recess on their internal face receiving a bridge forming a projection, these three parts being assembled by a screw through or by a double weld or brazing at the level of the recesses.
  • one of the plates has on its face internal a prominence forming a projection coming to settle against a prominence or in a recess made in correspondence on the internal face of the other plate, these two parts being assembled by snap-fastening, or by a screw or through a pin or by a weld or solder at the level of the hollow.
  • the plates and the jump bridge are machined in one piece, and a passage between the light and the edge of the flat end of the branch for installation of this sliding part in front of the spring previously installed in the light.
  • Either variant is relatively easy to make and to assemble, which further reduces manufacturing costs.
  • the sliding external part has a cross section in U or O whose internal passage corresponds to the external shape of the flat end.
  • the sliding part can then be assimilated from a point of view aesthetic to a decorative ring surrounding the end of a flat branch, ring thin or thick whose shape of the external envelope can, if desired, elegantly extend that given to the female knuckle.
  • the part sliding and the light is crossed in front of the spring by a stopper pin forming a male projection.
  • This stopper pin may have a cylindrical part held by clamping in the openings of the external part, and a conical part introduction connected to the cylindrical part by a breaking bridge. The pieces of this mechanisms are simple to make and are assembled in a conventional manner.
  • the internal passage of the sliding part has, at the level of the light, a cavity corresponding to the contour of the spring ending in front of this spring by a female jump.
  • the spring is partly contained in a barrel sleeve within the light, this socket having a low coefficient of friction with the spring material to avoid any risk of buckling during its compression, and ensure smooth relaxation.
  • this socket retains the external U-shaped part against a lateral escape in place of the spring, which avoid trapping it.
  • FIG. 1a is illustrated a hinge connecting a first side 4, by example a front tenon of a spectacle frame, on a second side 6, by example a spectacle frame branch, it being understood that the two sides can be interchanged, the first side 4 then becoming the branch and the second side 6 being the front tenon.
  • This hinge includes a male knuckle 10 engaged between the upper and lower eyelets of a female knuckle 20 to which it is connected by a connecting pin 12.
  • the end 14 of the second side 6 carrying the male knuckle 10 has a flattened shape, in particular oriented horizontally, that is to say that its width is significantly greater than the height forming the thickness of this male knuckle.
  • An elastic mechanism of recall of the hinge is then formed on the one hand by the periphery in cam 22 of eyelets of female knuckle 20 having at least two right and left angles joined by a straight edge against which a piece is pushed on the other hand external 30 sliding on the large face of this end 14.
  • a long rectangular light 16 through is pierced in the thickness of the end 14 little behind the orifice 11 for passage of the axis 12 of connection of the hinge and this in the direction of the length of the second side 6.
  • an elastic return means in particular a circular helical spring 18, this means also being able to be a spring square section, even a block of elastomer.
  • This spring 18 bears against the bottom rear 8 of this light, that is to say the end opposite to the orifice 11 of passage connecting axis.
  • the external part 30 is composed of a plate upper 31 and a counterplate 32 joined together by a jump bridge 35 passing through the light 16 in front of the spring 18.
  • the internal faces of the plates 31 and 32 are provided to at least cover the light 16 so as to enclose and hold the spring 18 in place in this light.
  • the external contours of the plates 31.32 are left to the free choice from the designer of the hinge aesthetic. In particular, these external contours may have streaks, beads or other decorative engravings.
  • at least one of the front edges 38,39 and preferably these two edges front plates respectively 32 and 31 are straight in correspondence with female knuckle cam face 22.
  • the bridge 35 for connecting the plates 31, 32 can be a part independent or, as illustrated, formed for half in the internal face of each of the platelets, or belong to only one of the platelets, the other having in correspondence, a set-up recess.
  • An orifice 36 passing through the plates and the bridge 35 allows the external part 30 to be securely assembled. Also consider that the junction faces facing the half-bridges 35 are provided with a tenon connection protruding from one of the faces snapping into a groove on the other side.
  • the rear face 34 of this bridge 35 forms a male projection, that is to say constitutes a step or projection or protrusion protruding from the internal faces platelet planes, projection against which the spring 18 pushes, thus pressing the external part 30 against the female knuckle 20.
  • the two plates and the jump bridge are machined in one piece. According to one first variant, it is then necessary to provide a transverse passage in the middle of the housing up to the side edge of the flat end for installation of this part external sliding, the spring being previously compressed in the rear half housing, for example by means of a wire.
  • the return mechanism is based on a monobloc sliding part 30 ′ illustrated in FIGS. 1c and 1d.
  • This 30 'piece can be made by milling two grooves in the lateral faces of a metal block releasing and separating the two upper plates 31 'and lower 32', the gap left between the grooves forming the bridge 35 '.
  • the light 16 is then extended to the front edge of the end plate 14 of branch by a passage 17.
  • an opening 19 is provided transversely to this passage 17, shortly after the frontal limit of the light 16.
  • This opening 19 is here illustrated rectangular, but could have other shapes as soon as it is wider than the passage 17.
  • This opening 19 is provided for receive a block 3 of external dimensions corresponding to those internal of this opening, block in which the passage orifice 11 of the connecting axis of the hinge.
  • the assembly then consists in install the spring 18 in the light 16, then insert in the passage 17 the bridge 35 'of the part 30' which is then slid into the light 16 by compressing the spring 18 until clearing the opening 19.
  • This block 3 is finally locked in position by the two eyelets of the female knuckle 20 assembled to the male knuckle by means of the hinge connection axis.
  • FIGS 2 illustrate a second embodiment of the hinge according to the invention in which identical reference numerals designate similar parts.
  • This variant stands out in particular in the geometry of the sliding external part 40 which here has a U-shaped transverse shape surrounding partially the flat end 14 on side 6.
  • this external part 40 has therefore an internal passage 42 substantially parallelepipedic whose height corresponds to the thickness of the end 14.
  • this internal passage 42 includes a blind cylindrical cavity 46, that is to say ending in two female projections 44. This makes it possible to install in the light 16 a spring 18 'of diameter substantially greater than the thickness of the flat end 14.
  • the front face 48 of this part 40 is also flat in correspondence with the rectilinear part 22 of the cam periphery of the eyecups of the female hinge 20.
  • this external shape of part 40 can elegantly extend the shape external of the female knuckle 20 as better visible in FIG. 2a.
  • a rotation action of sides 4 and 6 around of their connecting axis 12 means that one of the two cam angles of this knuckle pushes back the part 40 by compressing its internal spring 18. As soon as this stress is removed, the spring 18 forces the sliding external part 40 to stabilize against one of the straight edges of the female knuckle 20.
  • Figures 3 illustrate a third embodiment of a hinge according to the invention in which the sliding external part 50 envelops completely the flat end 14 on the side 6, that is to say that this part is presented in the form of a ring of substantially O cross section.
  • the passage internal 52 of this ring is parallelepipedic with its dimensions corresponding to the external ones of the flat end 14 on the side 6.
  • the spring 18 is then entirely contained in the housing 16 and a through hole 56 is provided in the ring 50 for a pin 54 passing in front of the spring 18, this pin thus forming a male projection receiving the spring thrust.
  • the dimensions and shape of the outer shell of this ring 50 are at the discretion of the designer the aesthetics of the hinge and can, as illustrated in Figure 3, advantageously extend that of the female knuckle 20, these two parts being separated by a plane comprising the front support face 58 of the part 50.
  • FIGS 4 illustrate a fourth embodiment of a hinge according to the invention in which the housing 16 formed at the flat end is no longer oriented towards the side 6, but is arranged starting from the orifice 11 for passage of the axis link 12 of the hinge to the front periphery now in the form of 10 'male knuckle cam.
  • This periphery of male knuckle presents at least two flat faces 13 and 15 separated by an angle forming between them the cam.
  • this 10 'male knuckle is therefore a little longer, and it is the same for the eyelets of the corresponding female knuckle 20 ′.
  • front edges 38, 39 of the pads are, within illustrated examples, rectilinear in correspondence with the rectilinear portions of angular peripheries of female knuckle-eyes, we can also consider these front edges are convex in correspondence with portions concave peripheries of eyecups.
  • the rear part of the spring pressing against the bottom of the housing can be contained inside a bush made of a material having a low bending coefficient with that of the spring such as copper or Teflon, this bushing preventing buckling and / or jamming of the coils of the spring against the side walls of the housing.
  • the invention is also not strictly limited to the application of a flat arm of glasses oriented horizontally, but can also be adapted to a vertical branch.
  • the male and female knuckles are then found perpendicular to the branch, and it then suffices to thicken the front edges 38,48,58 sliding external parts 30, 40 and 50 so that they can come into action against the cam periphery of the female knuckle.
  • the constituent parts being relatively simple structures, they are preferably machined from metal to obtain very small hinges dimensions, therefore very aesthetic.
